Laptops contain a lot of proprietary tech, not all is well supported. It's not all bad though: Chromebooks run some version of modified Linux just fine (and the trackpad of the original Pixel works great). My Dell M6800 (Ubuntu 'certified') is well supported and runs cool. It's an age-old, but often ignored advise to first consider one's needs and then chose fitting soft- and hardware. Instead people just go out and buy cheap or shiny and then wonder what to do with it ;-}
